Cis- cu gly 2
WebThe thermal decomposition reactions of the complexes cis/trans - [Cu (gly) 2] • H 2 O were studied by TG-DSC methods. The results showed that they have similar decomposition process, which occur in two steps. The first step is the loss of water and the second step is the decomposition of anhydrous complexes.
